1
Q

what is the definition of early ejaculation in men?

A
  1. an inability to control ejaculatory time in the majority of situations
  2. this causes distress
  3. mean time to ejaculation is < 1 minute prior to penis entering the vagina or < 3 minutes if penile penetration has occurred

Note all the studies have only looked a cis male heterosexual couples…

Q

what are some of the causes of PE (Premature ejaculation) and how could you categories them?

A

we don’t know what the cause is of PE in the majority of cases
it can be acquired or lifelong

Lifelong causes –> patients may have just failed to learn the ability to control ejaculation, it could be inherited or it could be due to 5HT dysfunction

Acquired causes:

  1. psychological
  2. relationship issues
  3. social pressure
  4. organic causes - chronic pelvic pain in men, benign prostatic hypertrophy, erectile dysfunction, endocrine or neurological causes

Q

You diagnose Ben a 36 year old male with premature ejaculation. He is keen to try some medical treatment - what is the first line option you would consider?

A

Topical EMLA cream - apply FTU to the frenulum 10-20 minutes before sex, ensure they use a condom otherwise can affect partners ability to orgasm
it is trial error sometimes need some more sometimes less and it is a process of finding what helps for Ben

usually use this in conjunction with psychological support e.g. stop and start technqiues in sex therapy

A

previous MI or stroke within the last 90 days
concurrent use of nitrates, including GTN or nitrate poppers as recreational drugs

Q

How do PDE 5 inhibitors work to help maintain an erection

A

PDE 5 inhibitors work to block the enzyme PDE5 that would break down cGMP levels. This leads to an increase in cGMP levels that works to induce smooth muscle relaxation in the BVs to increase blood flow into the penis.

Q

in PE prior to trying PDE 5 inhibitors what other class of medications might be useful to try and help to delay ejaculation

A

Anti-depressants specifically SSRIs ( fluoxetine and paroexteine are all off licence for this indication, taken daily)
only SSRI licensed for this indication is dapoxetine

A

history - ask what they mean, is it lifelong or acquired, global or situational, pmhx, and drug hx very important, talk about their relationship etc
examination - genital examination, consider prostate exam if relevant, may need neuro exam, BP, BMI,

investigations - everyone should have CVD check - glucose/hba1c, lipids, total testosterone, consider TFTS, prolactin, FSH/LH and PSA if relevant to the history

calculate Q risk 3

Q

what is alprostadil and how does it work?

does it have to be injected into the muscle or urethra or are there any other ways to give the medications

Q

what is responsive desire?

A

Responsive desire describes a situation in which you become sexually aroused. You didn’t desire to have sex but you respond to a sexual stimulus e..g you are washing the dishes and your partner starts to kiss your neck.. you then become aroused and go on to have sex. This is normal = responsive desire.

However a lot of patients attend thinking they lack spontaneous desire.

  2. TCA (tricyclic anti-depressants) e.g. amitryptiline 10mg OD (up to 60mg normally)
    others include - gabapentin and pregabalin

these medical Rx should be used alongside non pharmacological treatments including mindfulness, specialist women’s health physiotherapists

37
Q

how common is vaginismus?

A

affects about 12% of women so it is common!

38
Q

what is vaginismus?

A

an involuntary contraction of the musculature of the outer third of the vagina interfering with intercourse, causing distress and interpersonal difficulties.

it is more of a clinical syndrome

39
Q

How does vaginismus cause difficulties when having sex?

A

Vaginismus leads to the involuntary contraction of the pelvic floor muscles which leads to an inability for penile penetration and in some cases even digital penetration. This causes pain and then fear and viscous cycle.

40
Q

what causes vaginismus?

A

we don’t know! in a large proportion of cases patients may have had previous bad experiences including sexual abuse

41
Q

What is the management approach to vaginismus?

A
  1. stop the pain cycle –> pscyhological help
  2. pelvic floor assessment & physiotherapy to try and help get the pelvic floor to relax
  3. self exploration with fingers/ vaginal trainers (previously called dilators) to try and desensitise the pain and fear

52
Q

what are the routine investigations needed to investigate for causes of ED

    bloods: lipids, HbA1c or fasting BG
    (calculate Qrsik3 = 10 year risk of CVD)

early morning total testosterone 9am-11am, fasted sample ( if low then repeat + do FSH, LH, SHBG, prolactin)

Not routine:-

only do PSA if LUTS symptoms, or due to LUTS you have done a prostate exam and feel it is required (also need to do PSA prior to starting testosterone therapy)

only do TFTs if symptoms suggestive, LFTs/U&Es if symptoms or concerns - not routine

53
Q

David is a 56 year old man. He comes to the GP stating he hasn’t been able to ejaculate for the past 6 months. He is able to get an erection and gets the sensation of orgasim but no ejaculate. He had a TURP for BPH 9 months ago. What do you think is the diagnosis:

a) absent ejacualtion
b premature ejaculation
c) retrograde ejaculation
d) erectile dysfunction

A

c) retrograde ejaculation

54
Q

what conditions/ surgical Rx
pharmacological causes
medical problems that can cause retrograde ejaculation

A

BPH
DM -autonomic neuropathy
MS

Surgical:
TURP
prostectomy
retroperitoneal lymph node resection
bladder neck surgery

drugs e.g. alpha adrenergic blockers

55
Q

how can you confirm retrograde ejaculation

A

centrifuge urine 10mins post presumed ejaculation

56
Q

how can retrograde ejaculation be treated

a) EMLA cream
b) dapoxeteine
c) alpha-agonist (e.g. pseudoephedrine)
d) PDE5 inhibitors e.g. sildenafil

A

c) alpha agonist e.g. pseudoephedrine, epidrine or midodrine (these are second line after TCA - imipramine

57
Q

how might a cis-male patient present with retrograde ejaculation

A

‘dry’ ejaculation or low volume of ejaculation
post void urine after orgasm might be very cloudy

58
Q

what is the pathophysiology of retrograde ejaculation

A

usually during ejaculation urethral pressure > bladder pressure and the sphincter to the bladder closes, however for some reason this doesn’t happen and seminal fluid travels back into the bladder

often secondary to recent surgery e.g TURP, bladder surgery or retroperitoneal lymph node resection/retrieval

59
Q

what is first line Rx option for retrograde ejaculation

a) sildenafil
b) doxasocin
c) tamsulosin
d) imipramine
e) dapoxeteine

A

d) imipramine (TCA) first line

second line is alpha adrenergic receptors (all end e.g pseudoephrine)

60
Q

what class of medications can cause retrograde ejaculation

A

alpha adrenergic blockers e.g. tamsulosin, suffix “-osin.” These medications include alfuzosin, doxazosin, terazosin, tamsulosin, and prazosin

all used to Rx BPH. aim to reduce bladder tone. whereas in retrograde ejacualation we want to increase it.

61
Q

what is Odynorgasmia or dysorgasmia

A

painful ejaculation

62
Q

what conditions are associated with painful ejaculation

A

CPPS (chronic pelvic pain syndrome)
prostatitis
bph

management involves addressing the cause

63
Q

Ashley is 52 years old. He presents to his GP with painful erections and says he thinks he can feel a lump in the midshaft of the penis. He has noticed when he gets an erection the penis looks curved and it is extremely painful.

What do you think is the DD?

a) Retrograde ejaculation
b) CPPS
c) Peyronie’s disease
d) Prostatitis
e) Erectile dysfunction

A

c) Peyronie’s disease

64
Q

what causes Peyronie’s disease

A

we don’t really know
thought due to development of scar tissue that develops into plaques underneath penile tissue, causing a curvature of the penis with an erection. Very painful erections.

65
Q

how can we Rx Payronie’s disease

A

High dose Vit E and Potaba (potassium aminobenzoate) frequently tried with minimal response.
Surgical intervention (Nesbit’s procedure) to straighten the penis.

Patients with significant deformity and ED may require a penile prosthesis to be inserted.

66
Q

what is retarded ejaculation

A

absent or difficulty to ejaculate (note not retrograde ejaculation)

67
Q

what are the common causes of retarded/absent ejaculation

A

often thought to be psychological but need to rule out:

  • neurological (DM, MS, SC injury)
    -hypogonadism
  • hypothyroidism

can also be caused by medication:

SSRI, alpha blockers (doxasocin, tamsulosin)

68
Q

management of retarded/absent ejaculation

A

often difficult to Rx -

  1. psychological support
  2. no licenced medication, nothing found of benefit in terms of medical Rx
  3. if spinal cord injury - low grade shock wave therapy
